SPOKE-SWAGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 503,791, dated August 22, 1893.

' Application tiled April 4, 1893. Serial No. 46 8,970. (N o model.)

To @ZZ whom. it may conce-rn.-

Be it known that I, PETER GENDRON, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Spoke-Swaging Machines, of which the following isa speci iication, referencebeing had therein to the accompanying drawings.

The invention consists in the construction of a machine comprising swaging dies, actuating mechanism therefor, a chuck or work holder having means for moving the work across the dies.

The invention further consists in the peculiar construction of the dies, their adjusting devices and actuating devices; further in the peculiar construction of the feed mechanism for the work, and the means for stopping and starting it.

The invention consists in the peculiar con-` struction, arrangement and combination of the various parts, all as more fully hereinafter described.

In the drawings, Figure l is a front helevation of my machine. Fig. 2 is a vertical, central section through the upper die or hammer and its actuating mechanism, partly in elevation. Fig. 3 is a section at right angles to Fig. 2 through some of the same parts. Fig. 4. is a horizontal section through the feed shaft and its actuating mechanism. Fig. 5 is a cross section on line a: x, Fig. 4. Fig. 6 is a detached perspective view of one of the adjusting rings for the anvil die. Fig. 7 is a similar perspective view of a locking plate therefor. Fig. Sis an elevation illustrating the work of the machine, and Fig. 9 is a detached perspective view of one of the upper dies.

A is a suitable standard supporting the operating parts of the machine. This standard has a curved arm or head B arching over the top of the standard and leaving room for the Working of the dies, as is usual in such machines, and a side bracket C for supporting the actuating mechanism of the feed shaft to be hereinafter described.

l is the anvil block supported in guide ways 2 at the top of the standard.

3 is a stem or shaft extending downwardly from the under side of the anvil block and having nuts 4 to prevent its disengagement.

The anvil block is adjustable by means of the rings 5 and G, sleeved upon the stem 3 and having corresponding spiral cam ways 7 upon their meeting faces. The ring 5 has any suitable means of adjustment with alocking device for holding it in its adj usted position. I have shown a series of notches or teeth a on its upper edge with which a locking plate 8, having corresponding teeth is adapted to engage. This plate is adapted to be clamped upon the ring by means of the set screw 9 which engages into the side of the anvil block l. The lower ring 6 is adapted to be turned upon the stem 3 and this end is provided with a hand lever l0 projecting to the front in convenient proximity to the operator. I Y

' 1l is a latch pivoted on this lever, and l2 is a spring pawl adapted to engage with the Vlatch to hold the ring in its adjusted position.

By turning the hand lever until it engages with the spring pawl, the anvil die will be raised into proper position to be operated upon by the hammer die 14e. This hammer die is supported on the lower end of the head l5 sliding in suitable guides 16 in the arm B of the standard. This sliding head is supported by means of the link 17 from the cross spring 18, the link being pivoted at its lower end upon the pin 19. The tension of the spring may be adj usted by means of the set screw 20. The head is provided with a longitudinal slot or opening 2l in the lower end of which is journaled the roller 22.

23 is a'drive shaft journaled in the arm B of the machine and passing transversely through the head l5, a slot 24 being provided to allow the head to have a suitable vertical` movement about the shaft without striking the same. 25 is a cam wheel secured on this shaft, preferablyof hexagonal form, as shown, with slightly rounded corners adapted to bear against the roller 22 in its rotation and depress the hammer die downward against the anvil die to swage the work. The shaft 23 is driven from any suitable source of power. It is evident that if work is placed in position upon the anvil die and motion is communicated to the shaft 23 the cam 25 at each revolution will depress the head l5 which will be lifted between the blows by means of the spring 18 and thus a very rapid series of blows IOO will be struck upon the work. In order to( swage a metal spoke, for instance, as in the manufacture of bicycles, in which the spoke 4ing 32.

is thinned through its middle portion and left of its original size at the ends, I have devised a feed mechanism which will continuously- I use YtheV word continuously in contradistinction to the feed the spoke between the dies.

intermittent feeding device. This feeding mechanism is driven preferably from a grooved wheel 26 lby means of a belt or rope 27 passing overidlers 28 and over a driven pulley 29 which is journaled on the sleeve 30-. This Vsleeve is supported on the screw shaft 31 which extends through a box 32 formed at the end of the bracket C. The outer end of the sleeve 30.is journaled in a bracket 39. The sleeve 30is'provided with an interior key 33 engaged in the key way 34 in the. shaft 31, so that when motion is communicated to the sleeve it will impart motion tothe shaft. The shaft at its forward end is provided with a socketed head 35, in which is secured theV forconnecting Vthe drive wheel 29 with `the shaft 3l.

43 is a screw block secured to the bearing 32 on one side thereof, and having a suitable screw threaded portion adapted to engage with the shaft 3l. held out of engagement with said shaft .by means of a spring 44 which forms in this case, the hinge for uniting the block to the bear- The screw block is provided with a hook 45 on'the side opposite to the spring 46 is a spring latch pivoted to the bearing 32. When the screw block engages the shaft 31 the hook 45 will engage over the latch 46 thus locking the screw block to the shaft. The parts being thus constructed, the work engaged in the chuck, as shown in Fig. 1,mo tion being imparted to the drive shaft 23, will likewise impart motion to the wheel 29, which will rotate upon the sleeve 30 without imparting motion thereto.

To start the machine, the operator grasps the hand-hold 41 and moves the clutch 42 into engagement with the wheel 29 which imparts motion through the connections described to the shaft 3l, rapidly ievolvingthe same. This shaft however, will not be fed longitudinally until the screw block 43 hasV been turned down to engage with the shaft, whenv the screwshaft will not only be rotated, but will also be fed longitudinally, drawing the work between the dies,which in the meantime have been moved into proper operative `feed of the shaft.

40 to elfect this movelnent.

This block Vis normally position as previously described. When the screw shaft 31 vreaches the i end of its movement, the inclined face 50 on the head 35 will strike the latch 46 and release .it from the hook 45 on the screw block, when the spring 44 will raise the screw block intothe position shown in Fig. 5, stopping the longitudinal Y A lThe operator may vnow stop the rotation of the shaftl by taking hold of the wheel 4l and drawing itlaterally to the position shown in Fig. 4, disengaging the clutch. In this position the swaged blank maybe removed from the chuck, a new one inserted and the shaft pushed through its bearing to its initial position, as shown in Fig. 1, the operator pressing upon the' knob To again start the feedthe operator presses in uponthe i hand wheel 41, re-engaging the clutch' and starting the shaft revolvingand then presses down the screw,l block. In inserting a new blank the lower die or anvil is lowered by means of the lever 10 as previously described and in starting the operation it is raised to its operative position.

I find that with a swaging machine of this kind I am enabled to swage spokes for a bicycle not only most satisfactorily as to the work produced but, with greatspeed, thus 'simplifying and cheapening the production of such spokes.

What I claim as my invention is 1. In a metal swaging machine, the combination with the dies, of a chuck, a screw shaft onwhich the chuck is mounted, a bearing for the shaft-7 a screw block on the bearing engaging the shaft, a spring for disengagingthe block from the shaft, atrip for releasing the spring and an abutment carried directly by the shaft for engaging the trip substantially as described. g ,Y Y j 2.

Y

3. In a metal swaging machine, the combination with a hammer die, of an anvil die, and means for adjusting the anvil die, consisting of a plurality of cam rings, means for adjusting oneringindependently of the other, and a lever for moving the other ring, substantially as described.
